Molecular association of polypeptides in concentrated solutions investigated by the electrooptical method

摘要: Abstract From the saturation effect of electric birefringence in PBLG-dichloroethane systems at various concentrations, values dipole moment and optical anisotropy factor were obtained, average relaxation time rotational diffusion was obtained from decay process birefringence. The increased remarkably with increasing concentration pre-liquid crystal region, whereas did not. Above a critical solution became naturally birefringent week after. During this noticeable increases found. In order to make physical image concrete as what happening solution, length distribution functions derived curves conditions. results strongly suggest that cooperative growth molecular aggregates is groundwork formation liquid crystalline phase.
